Perry has now spoken out abut the prom revealing "I thought we were friends, that's why it was such a shock. I still have no idea whatsoever why she did it," she told the Sun
She bought the £500 ($750) ball dress, that is now ruined, and had her makeup professionally done for her prom. She had planned to travel to the event with a group of girls, one of whom was the bully, reported the Sun.
"I still have no idea whatsoever why she did it. It was so humiliating, it was in front of my whole year group," the teen added
She explained that lots of teachers who realised what had happened tried to console her in an attempt to persuade her to remain at the prom.
Her mother added that the school, Hall Cross Academy in Doncaster, knows about the brutal act and said they would get in touch but have not so far.
Perry also told the Sun that she hadn't heard from the "friend" and doesn't expect to ever see her again, as their school exams are over.
The 16-year-old had reportedly left a previous school due to bullying and has suffered from anxiety since she was 10.
The teen also took to Facebook to express her gratitude after receiving messages of support from around the world.
"The way that people have responded has absolutely overwhelmed me," Perry posted on Facebook, which has over 17,000 likes.
"I hope that this makes me a stronger person. I'm personally making the decision to keep the name of the girl anonymous because I would HATE to be spreading her name around and causing her more hate and stress."
